Top five cheap mattresses for 2019
By Ben Slater
Great cheap mattresses are few and far between, but choose carefully and you can get a good night’s sleep for the equivalent cost of five pence per night.
Buy a pricey pocket-sprung or memory foam mattress and you’ll sleep soundly on it for so long that it will work out better value for money than a cheap mattress that will sag and soften within a few years. Or so they say.
And yet, time and again our expert tests have conclusively proven that while spending more may get you better quality materials, such as silk and cashmere, it doesn’t guarantee superior support or stability.
We’ve tested mattresses costing £1,500 – the equivalent of more than 40 pence per night for 10 years – that are less supportive and long-lasting than mattresses costing £200 – or five pence per night for 10 years.
We’ve tested good and bad mattresses at every price point so, however much you want to spend, make sure you check our full list of Best Buy mattresses.
Top five cheap mattresses for 2019
All of the mattresses we’ve picked out below cost £300 or less and all of them are Best Buys. That means that, at the very least, you can rely on them to support your spine for years to come, without sagging or softening.
If you want a cheap mattress but don’t know which type to choose, you’ll want to consider this one. It contains layers of foam, memory foam and pocket-springs and it’s clearly a winning combination – this is the best cheap mattress we’ve seen and the joint-fifth highest scoring mattress overall. It provides an impressive level of long-lasting support, especially if you sleep on your back, and it’s great at preventing movement from transferring from one side of the bed to the other, making it suitable for light sleepers.
As you might expect at this price, this mattress isn’t stuffed with luxurious fillings such as silk and cashmere. In fact, it’s little more than a lump of foam. What you might not expect for the price, though, is a mattress that provides good support for your spine without restricting your movement, and will remain more or less unchanged after years of use.
If you’re looking for a cheap memory foam mattress, you’ll want to add this one to your shortlist – especially if you sleep on your side or need a new mattress in a hurry. While it’s supportive for everyone, it’s particularly well suited to side sleepers. It comes vacuum packed, so you can try it out in store and take it home the same day. If you like the feel of it in the shop, you can be confident that you still will in years to come, because it doesn’t sag or get softer with time.
Perhaps the best-value pocket sprung mattress we’ve ever seen, this excellent option will provide good all-round body support for years to come. That’s not all, as it’s also breathable, easy to roll over on and stable – that means you’re less likely to be disturbed if your partner gets up during the night. Finally, it’s lighter and easier to manoeuvre than many other pocket sprung mattresses, which you’ll be thankful for when you rotate it from head to toe or move it into another bedroom or home.
This reasonably priced memory foam mattress is a great all rounder. Whatever your size or sleeping position, this mattress does a good job of supporting your spine, and it’s exceptionally supportive for smaller people who sleep on their backs. It’s worth considering if you or your partner are light sleepers, because it’s really good at absorbing bounces. The only things to bear in mind are that this mattress restricts your movement a little more than some we’ve seen, and, although the quality of support doesn’t deteriorate, the mattress will get slightly softer with time.
Which? mattress reviews
You can have complete confidence in our mattress recommendations. Not only are we completely independent and impartial, but every mattress we test is subjected to an extensive series of lab tests, all of which have been designed by mattress experts.
Our body support tests, for example, use special equipment to measure the shape of our test subjects’ spines at 36 different points. When you’re lying on your back, a good mattress should keep your spine in the same shape as when you’re standing, while your spine should be parallel to the mattress when you’re lying on your side.
We also accurately measure the firmness, warmth and breathability of mattresses, as well as dropping weights on them and measuring the bounce to see how stable they are. A stable mattress will be good at preventing movement from transferring from one side of the bed to the other, ideally without making it more difficult for you to roll over and switch sleeping positions during the night.
After all this, and more, we simulate up to 10 years of use by rolling heavy human-sized barrels over each mattress thousands upon thousands of times. We then do our body support tests all over again to see how it’s changed, while also assessing each mattress for sagging and softening.
